Counties with the most pre-war homes in New Hampshire

Pre-war homes—those built before 1939—are architectural gems. They are sturdy, charming, and often what people are referring to when they look at the prevalent colorless, linear designs of today and lament "they just don't make them like they used to."

In some ways, that's a good thing. Pre-war homes often contained materials we know to be hazardous today, like asbestos and lead. But their signature characteristics, including hardwood floors, nickel accents, ornate crown molding, and high ceilings, are among the features many people look for in a dream home.

Preserving the history of these properties, many of which you'll find on the National Register of Historic Places, is labor that often extends beyond the scope of an individual homeowner. Depending on where these homes are located, special permission by local historic commissions may be required before renovations can be done in an effort to preserve their historic architectural integrity.
